Grading team selections has become as big a part of the post-NFL draft evaluation process, as mock drafts and preview shows are in preparing for it. Everyone wants to know how their team did.

Unfortunately, we have no way of knowing how any of the 32 teams did in the draft. Grading each team's selections is simply an exercise in predicting future returns and weighing perceived value.

For many prospects who were lucky enough to be selected by an NFL franchise, the windows for success and failure are very small. For others, making a name in the NFL could take several years of flying under the radar with little expectation for success.

What that all means is simple: Draft grades mean very little. Everything will change when players take the field this fall.

But there is some value in grading picks. Specifically, we can break down how teams shored up needs with good value picks and made the most of their draft picks.

Let's take a look at grades for all 32 teams and discuss a couple of teams that did extremely well in the 2013 NFL draft.

San Francisco 49ers (A)

The San Francisco 49ers had plenty of ammunition to make a splash in the draft. They entered the process with 13 selections, using 11 of them and packaging others to move around the draft board. It was the perfect scenario for a team with few holes to fill.

The 49ers made the most of its picks, moving up to No. 18 in the first round for a player they really wanted in LSU safety Eric Reid. While draft analysts may not have seen the value in taking Reid so early, it was obvious the 49ers really wanted Reid.

San Francisco followed that selection with a tremendous value pick in Florida State defensive end Tank Carradine at No. 40 and Rice tight end Vance McDonald at No. 55, both in the second round.

Third- and fourth-rounders Corey Lemonier, Quinton Patton and Marcus Lattimore were equally impressive picks, as the 49ers balanced the need for depth and the sheer value of where they were selecting.

Baltimore Ravens (A)

It’s only fitting the Baltimore Ravens would join San Francisco on this list. There’s a reason the two teams met in the Super Bowl last year.

Teams that draft well enjoy the most success in the NFL, and Ozzie Newsome drafts as well as any general manager in the league. He certainly did his job this year.

Baltimore selected Florida safety Matt Elam at the end of the first round (a good pick filling a major need), but its best selection came on Day 2 and the 56th pick. Newsome used that selection to lock up Kansas State linebacker Arthur Brown—a player some believed to be the best inside linebacker available this year.

Newsome continued his momentum by finding some tremendous value throughout Days 2 and 3, and he took advantage of that value by selecting players who filled positional needs. Elam, Brown, Brandon Williams (No. 94) and John Simon (No. 129) should all see considerable time on a defense that desperately needed some fresh faces this offseason.
